In this modification annular outer hoop portion 3 which has a sethe band hides the bead and'searn and exposes ries of serrations or iingers 4 on one edge as the hoop to view from the rear.

Y g j P in to receive the prongs of a spanner or tightening tool. On moving these prongs together' by sufficient application of power the ends 24 and 25 are brought closer together and the band tightly grips the annular member 3. A hole is then drilled or otherwise formed through the end 25 the tongue 23 there beneath the annular member 3 and the plate 9. The parts are then held in position by a rivet or other suitable fastener 27.

I mayof course forml the holes-for the rivet in the separateparts before the hoop is applied to the member 3 but I prefer to make this rivet hole at least through the parts 23, 3 and`9 after the hoop 22 is clamped in position as this ensures that it will always be tightly positioned on the memberf3.

To place the tire cover in position on a spare tire the nger piece 15 is grasped and the handle 15 rotated to the position shown in dotted lines yin, Fig. 4, the binding post 16 turning in the handle during this operation. This movement forces the wire 8 through the channels in the serrations 4 around the circumference of the cover and expands them so that the cover can bereadily passed over the spare tire. The wire may not pass through a few of the serrations such as 28 to permit the wire 8 more readily to perform this expanding movement. These serrations, however, are quite flexible like the others and they offer no impediment to the placing of the cover on the tire. It is also permissible to leave this portion of the cover -in solid form, that is unserrated.

f The handle 15 is then rotated in theopposite direction to the position shown in Fig. 4. ThisV movement of the handle draws the wire 8 through the serrations 4 and forces them tightly down against the side of the tire. This holds the tire cover firmly in place. v

As a further modification I have omitted the tongue portion 23. One then drills an additional hole through the hoop 22, the vannular member 3 and the strengthening plate 9, after the band is drawn tightly in positionfas already described, and fastens a second rivet 27 therein.

Instead of using rivets 27 and 27 Ivmay spot-weld the ends 24 and 25 in place or otherwise fasten them lightly in place on the cover. 1

Instead of placing the noop in position be- 56 tween the beads 2 and 6, I may construct it to overlap the same as'shown in Fig. 5. In Figs. 6 and 7 I have shown a further modified form of positioning means. I have secured spring clips 4 at spaced intervals around the member 3 for example at intervals of 45 and secured inside against the inner surface of band member 3. With this form o f clamping means the clipsL will expand to open position through their own resiliency when the draw member is released.

The draw member 8 in this case need not be a spring Wire but may be an ordinary soft wire or veven a stranded cable or a cord. In this modification I have shown a different clamping means but by way of example only.

The wire 8 passes through a stud 30 in a hole therein and the thumb nut 31 clamps the washer 32 down upon the draw member 8 to hold it in place. This stud is secured to the plate l1 which is hinged to the plate 9. On pulling on the ring end 33 the spring clips are drawn down on the tire and the cover is rigidly held on the tire. The wing nut on being screwed down holds this adjustment. On loosening the wing nut the spring clips spring outward and draw the member 8 or tend to draw it, back through the clamping stud 30 so the tire can be removed. In case themember 8 is a wire this movement may be aided by pushing on the ring 33 to permit the clips to expand. Also if the friction of the member 8 in the clips retards the expansion of-these clips, an outward pull on the tire to'remove it will aid in retracting the draw member. y l

The fastener 30, 31 may alsobe used' in the construction shown in Figs. '2 to 4 inclusive. 7

An advantage of my metallic` tire cover is'that it furnishesv a stronger cover than the usual fabric cover, is free from the usual wrinkles of a fabric cover andV may be metal plated, painted or otherwise decorated to harmonize or contrast with the finish of the automobile. f The strengthening hoop 22 may be painted or metal plated differently from the remaining part of the tire cover in some cases and the use of thisextra reinforcing hoop makes it easy to produce this contrast7 particularly in case of metal plating. In such case the hoop 22 maybe plated entirely separately 4from the other parts.

Instead'of making the strips 4" in the form of springs I may make themlike the membersll, 9 of Fig. 7 that is, the strips 4 may behinged to the cover. In this case it would be necessary vto use a stiff Wire 8 to spread the hinged strips in opening the covers. A i

Having described my invention, `what I claim is: 1. In tire covers, an annular band adapted lto surround a spare tire, fingers spaced free ends of said fingers and means to contract the draw member and hold it in contracted position to move and hold the lingers against the tire.

3. In tire covers, an annular band adapted to surround a spare tire, spaced gripping members substantially housed inside said band and a Wire passing through the ends of said members adapted to move them against the tire to hold the cover thereon.

In testimony whereof, I have signed my name to this specification this 30 day of March, 1931.
